Description

Technical Field

[0001] The utility model relates to the technical field of special medical devices for stomatology, and particularly relates to a dental implant scanning rod presser. Background Art

[0002] An implant scanning rod is a digital tool used in dental implant surgery. The implant scanning rod plays an important role in dental implant surgery, mainly used for oral scanning, model making, surgical guidance, etc. Its working principle is based on digital oral scanning technology and an accurate positioning system. By connecting a positioning member and an oral scanner, a digital oral model can be made, providing a basis for the planning and design of implant surgery. The specific shape and size of the implant scanning rod can provide accurate positioning information of the implant, helping doctors accurately locate the position and angle of the implant, thereby improving the accuracy and safety of the surgery.

[0003] With the popularization of oral digitization, implant restoration is increasingly widely used in the field of dentistry. Installing an implant scanning rod is an important step in the second-stage oral implant surgery or implant impression taking process. Currently, there is no special tool for installing an implant scanning rod on the market. Usually, a manual positioning and installation method is adopted, that is, one hand uses fingers or other non-special tools to press the scanning rod, and the other hand tightens the central screw. However, the operation of pressing the scanning rod with fingers or other non-special tools easily causes the implant scanning rod or the screwdriver to fall off, posing a risk that the guest may accidentally swallow the implant scanning rod or the screwdriver may collide with the guest's oral cavity, which not only brings an unpleasant experience to the guest but also poses a medical safety hazard.

[0029] Embodiment 1

[0030] Refer to Figure 1 , the present utility model discloses a dental implant scanning rod presser, which includes a handle 1 and pressing parts 2 provided at both ends of the handle 1. The handle 1 includes a hand-held end 11 and a hand-held connection end 12 connected to one end of the hand-held end 11. The pressing part 2 includes a pressing end 21 and a pressing connection end 22 connected to the pressing end 21. The pressing end 21 is provided with a card slot 23, and the card slot 23 is adapted to the outer diameter of the scanning rod. The pressing connection end 22 is connected to the handle 1, and the pressing connection end 22 is connected to the hand-held connection end 12 of the handle 1.

[0031] Specifically, during the second-stage oral implant surgery or implant impression taking process, a medical staff member uses a dental implant scanning rod presser of the present utility model to press the scanning rod with one hand. The scanning rod is pressed by the card slot 23 of the pressing end 21, and the pressing part 2 is operated through the handle 1 to stably press the scanning rod on the implant. Then, the medical staff member uses the other hand to tighten the central screw, thereby installing the scanning rod on the implant. The present utility model provides a tool specifically for pressing the implant scanning rod, avoiding risks such as the falling off or accidental swallowing or aspiration of the scanning rod or screwdriver when using fingers or other non-special tools for pressing. By providing the handle 1 and the pressing part 2, and the pressing end 21 of the pressing part 2 is provided with a card slot 23 adapted to the outer diameter of the scanning rod, the scanning rod can be stably pressed, improving the accuracy and safety of installation.

[0032] Refer to Figure 1 , a first included angle 3 is provided at the connection between the pressing end 21 and the pressing connection end 22. The angle of the first included angle 3 is 115 - 135°. In this embodiment, the angle of the first included angle 3 is 125°. The plane where the handle 1 is located is set as the first plane, and the plane where the connection end of the pressing end 21 and the pressing end 21 is located is set as the second plane, and the first plane and the second plane intersect.

[0033] Specifically, the angle of the first included angle 3 is 115° to 135°, and the first plane intersects with the second plane. During the second-stage oral implant surgery or the implant impression-taking process, to a certain extent, it can make the operator's hand relatively deviate from the mouth when holding the hand-held end 11, thus leaving more sight lines, facilitating the operator to twist the central screw with the other hand, and improving the accuracy and convenience of the operation. At the same time, since the medical staff has more sight lines to observe the oral cavity, it also enables the medical staff to more accurately press the scanning rod when operating the pressing end 21.

[0034] See Figure 1 , the handle 1 includes a hand-held end 11 and a hand-held connection end 12 connected to one end of the hand-held end 11. A second included angle 4 is provided between the hand-held connection end 12 and the pressing connection end 22, and the angle of the second included angle 4 is 135° to 155°. In this embodiment, the angle of the second included angle 4 is 145°. Specifically, with the setting that the angle of the second included angle 4 is 135° to 155°, when the operator holds the hand-held end 11 and uses the pressing part 2 for operation, the appropriate second included angle 4 can enable the presser to better enter the oral cavity, and enable the hand-held connection end 12 and the pressing connection end 22 to cooperate with the tissues around the oral cavity, so that the hand-held connection end 12 and the pressing connection end 22 have better fitting and support with the tissues around the oral cavity (such as the lips, etc.), and can avoid the influence of the obstruction of the oral tissues on the sight line during the operation of the operator, so that the scanning rod can be more accurately pressed to the correct position.

[0035] See Figure 1 , the direction of the first included angle 3 at one end of the handle 1 is opposite to the direction of the first included angle 3 at the other end, and the direction of the second included angle 4 at one end of the hand-held end 11 is opposite to the direction of the second included angle 4 at the other end. Specifically, the oral cavity is divided into four regions, namely the upper left region, the upper right region, the lower left region, and the lower right region. The above design enables the presser to better adapt to the operation requirements of different regions in the oral cavity. For example, when operating in the upper left region, use the pressing part 2 at one end of the handle 1, and the directions of its first included angle 3 and second included angle 4 can enable the pressing end 21 to more accurately contact and press the scanning rod; when operating in the lower right region, use the pressing part 2 at the other end of the handle 1, and the same good operation effect can be achieved. Such a design improves the convenience and accuracy of the operation, enabling the medical staff to more easily complete the installation work of the implant scanning rod.

[0036] See Figure 1, the length of the hand-held end 11 is 100 - 120 mm. The hand-held end 11 is cylindrical, with a diameter of 7 - 9 mm. The length of the pressing end 21 is 5 - 8 mm, and the thickness of the pressing end 21 is 0.5 - 10 mm. The sum of the lengths of the pressing part 2 and the hand-held connecting end 12 along the straight line where the hand-held end 11 is located is 30 - 40 mm. In this embodiment, the length of the hand-held end 11 is 100 mm, the diameter of the hand-held end 11 is 7 mm, the length of the pressing end 21 is 5 mm, the thickness of the pressing end 21 is 0.8 mm, and the sum of the lengths of the pressing part 2 and the hand-held connecting end 12 along the straight line where the hand-held end 11 is located is 35 mm.

[0037] Specifically, the length design of the hand-held end 11 can meet the needs of different operators, making the operation more stable and comfortable. The hand-held end 11 is cylindrical with a diameter of 7 - 9 mm, enabling better fitting with the hand when the operator holds it and providing a good grip. The length design of the pressing end 21 can meet the requirements of the pressing operation, improving the pressing effect and accuracy. The appropriate thickness design makes the pressing end 21 not easily deformed during use and can stably press the scanning rod. Optimizing the overall length design of the pressing part 2 and the hand-held connecting end 12 improves the operation accuracy and convenience. Moreover, the overall structure of the presser is small and the shape design is simple, facilitating clinical operation.

[0038] See Figure 1 , the materials of the handle 1 and the pressing part 2 are stainless steel or medical plastic, and the handle 1 and the pressing part 2 are integrally formed. In this embodiment, the materials of the handle 1 and the pressing part 2 are stainless steel. The stainless steel material ensures the hygiene and durability of the presser, and the medical plastic material meets the one-time use requirement, reducing the risk of cross-infection. At the same time, both materials have low costs and are easy to promote and apply.

[0039] The implementation principle of this embodiment:

[0040] During the second-stage oral implant surgery or implant impression-taking process, medical staff select the appropriate pressing part 2 according to the operation area. For example, when operating in the upper left area, the pressing part 2 at one end of the handle 1 is used, and the directions of its first angle 3 and second angle 4 can make the pressing end 21 accurately contact and press the scanning rod; when operating in the lower right area, the pressing part 2 at the other end of the handle 1 is used. The medical staff hold the hand-held end 11, place the scanning rod into the card slot 23 of the pressing end 21, and operate the pressing part 2 through the handle 1 to stably press the scanning rod on the implant. Due to the design of the first angle 3 and the second angle 4, as well as the size settings of the hand-held end 11 and the pressing end 21, the operation is more convenient and accurate, while reducing the line of sight obstruction and the obstruction of oral tissues. The material selection of the handle 1 and the pressing part 2 ensures the hygiene, durability or one-time use requirement of the presser, reduces the cost, and is easy to promote and apply in clinical practice.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
